Have you ever had these red itchy bumps before? Are they familiar at all?
I don't know if it's an allergy or toxins. I know that whenever I start doing the b&p I break out in pimples...and sometimes get a headache.
Why not try some of these cleansing baths? I'd do one long hot one every day..your pick of either one. They will help to draw the toxins out of your body, if they are, indeed, signs of toxins.
Have you read the article Allergies on www.thedoctorwithin.com? Journey to the Center of the Colon is good too.
Let us know how this goes!
If your headache doesn't go away by drinking LOTS (up to 3 litres a day) of warm water - flushing out toxins - and you can't bear it, a simple asa aspirin will be okay to take. Not ideal, but if it's a matter of cleansing vs not cleansing, I'd take the aspirin!
